user11018: I have been practicing meditation for quite a long time now and sadly I haven't entered any jhana(which I want to enter).
I think the reason for me not progressing is because I switch between methods of meditation a lot, for example if I'm practicing meditation where I simply see my mind wandering and after a week or so I stop and look for another method, like focusing on nostrils and same happens for a week and then I start to look my muscles moving while breathing(I do that because I think I'm not good at this, maybe another one will work), as a result I don't get anywhere and day by day my faith that meditation is helpful gets less and less.
I don't want to do that! But I simply can't get any sort of guarantee that I am practicing right mindfulness.
So my questions:

1) Is this the reason I'm not progressing? Do I have to choose a method and stick to it, when my mind tells me to change?
2) While doing routine work, do I have to do work while being mindful or stick to my meditation object(nostrils, these days :((()? or being mindful and having focus on meditation object will have same effect?


user471: There's a nice online guide by Leigh Brasington called "Entering the Jhanas". It teaches how to enter the first jhana. Leigh Brasington studied under Ayya Khema and Jack Kornfield. Do take a look at this guide and read it completely. I think it will answer your questions satisfactorily.
Leigh Brasington also wrote a book called "Right Concentration: A Practical Guide to the Jhanas".
Another book on this subject is "Practicing the Jhanas: Traditional Concentration Meditation as Presented by the Venerable Pa Auk Sayadaw" by Stephen Snyder and Tina Rasmussen.

Jhana is a supernormal state. Very few people enter real jhana. Only Ajahn Brahm provides detailed teachings on real jhana.

(which I want to enter).

'Wanting' is the obstacle to jhana. The Buddha taught in SN 48.10 that jhana is reached by making 'letting go' the meditation object.

I think the reason for me not progressing is because I switch between methods of meditation a lot, for example if I'm practicing
  meditation where I simply see my mind wandering and after a week

If the mind is still wandering, it is pointless to think about reaching jhana. To reach jhana, the mind must have no wandering at all & even then it may take months of full-time practise to reach jhana. 

**or so I stop and look for another method, like focusing on nostrils and same happens for a week and then I start to look my muscles moving
  while breathing (I do that because I think I'm not good at this, maybe
  another one will work), as a result I don't get anywhere and **

To reach jhana, the mind must not have any of the five hindrances. Then, if that is so, the mind must let go and give up these techniques. The only way to jhana the Buddha taught was 'letting go'. 

day by day my faith that meditation is helpful gets less and less.

It appears you have wrong faith. Right faith in Buddhism is jhana is a supernormal state attained by extremely Noble & Virtuous Individuals, such as the Noble Sangha, who put supernormal effort & sacrifice into their practise. 
It sounds like your want for jhana is due to internet or consumerist advertising. Jhana is not like going to the department store to buy a fancy I-Phone or believing in Jesus for Eternal Life. 

I don't want to do that! But I simply can't get any sort of guarantee that I am practicing right mindfulness.

Wanting is the opposite of Buddhist practise. To reach jhana, there must be no hindrances, such as sexual desire & fear. 

1) Is this the reason I'm not progressing? Do I have to choose a method and stick to it, when my mind tells me to change?

The mind must be pure to reach jhana; particularly without sexual desire & sexual activity.

2) While doing routine work, do I have to do work while being mindful or stick to my meditation object(nostrils, these days :((()?
  or being mindful and having focus on meditation object will have same
  effect?

To reach jhana, full-time practise is required, such as meditating for 8 hours per day. 

user-1: Few suggestion I can give.

Don’t set the goal to get Jhana, No goal at all.
Don’t change the methods, Every methods was right it just a tool make you focus.
Do consistently. At least once a day and same time of the day.
Do anytime when you regcognize, Not just sit and shut your eyes.
Do when sleep until last moment you slept and do at very first moment you wakeup. This is an indicator that your meditation is progress. If you can continue the meditate from slept this indicate you are likely near Jhana.

Jhana is nothing special.
It's a state you can really control your concentration.
At initial step it's quite hard for people who are high skeptic or thoughtful with everything.
You don't need to take many hours everyday to sit and meditate.
You should try to take every seconds as meditate without distracting your work life.
Do until familiar then you reach Jhana.
Even it take 10 years still worth.
