Trump has done an absolutely admirable job of keeping his campaign promises, especially considering all the strident obstructionism he had to endure.

In just his first 120 days alone Trump has:

Reduced federal regulations
Withdrew from Trans-Pacific Partnership
Advanced the Keystone/Dakota pipeline 
Ended Obamacare fines
Implemented new lobbying ban
Strengthened the military
Temporarily froze the Federal workforce 
Deported violent illegal immigrants
Appointed a conservative Supreme Court justice
Getting tough on the Islamic terrorism
Renewed diplomatic relations with Israel.

Maybe you need to rethink your definition of empty promises, and realize who is actually gullible here.
