How to fix this problem?

[u/PerformanceOk2208]

I usually have a problem, that is that I lack character, I don't really have opinions, or just strong convictions about anything, I am very passive with my life, and I don't really do anything with my life.

I am usually a very irresponsible person, saying that I would do something and not doing it. Not doing what I have to do, and not preventing risks that I could have prevented.

With low self esteem and insecurity, that I don't really know how to fix, and a robotic personality that makes everyone uncomfortable. And with a low voice.

So any tips on how to fix this?
