Things usually don ' t work out if they are not for us or if timing and circumstances are not right . When nothing works out you might wanna consider change of direction . But before doing so , one needs to be kind to oneself . We all try our very best every day . And distance yourself from people who send out negative vibes . Surround yourself with those who appreciate you . I don ' t believe that there is a dumbest person alive but we all have days we feel this way i learn . If there is anything i don ' t understand , i read , i go to the library , i research until i understand . Hope that helps ! <| sep |> The real question is how long will the replacement modules be available , and how much do they cost ? If this product doesn ' t do well , will they stop making the replacement modules in a year ?
