How can we improve our personlity?

First you have to define who/where/what you want to be, then make a plan to reach this goal.
Don't try to reach everything at the same time: 1 step after the other with a lot of patience for yourself.
And don't forget to write it down and to read it if possible each day or change some of the points.
I am 44 and still do this. (nearly) Each night I check what I could have made better that day.
For me the most important is that I try to live my life and don't let others impose their opinions, life style, etc
And even more important, have fun and enjoy.
