What are some things to do for self-improvement that I am not doing? I've been doing cold showers for about one year now, yet not really noticing any major changes . What I mean is, people claim that they're more willing to get out of their comfort zone or whatever. I have not found this to be the case, even though I've always got the water temperature as cold as possible. I work out 4 times per week for about 30 minutes. I am a bit of an "introvert", too, always have been. Recently, I also got enough motivation to get a better job. I've tried meditation before (for about a year now, actually) and I don't notice any difference with meditation, besides feeling sleepy during and afterwards. I'm not overweight (I weigh about ~182-185 lbs.) either. Still, I know there's something I can do to improve myself, I'm not sure quite what, however. What do you do for self-improvement? Thanks.
