Guys, I'm looking for more personal challenges to take on, things that can be properly tracked; not things like smile more. Not hating on smiling more, but I just want to take a challenge where I can see visible progress. I consider NoFap to be one of the most life-changing personal challenges one can take up. Are there any other such challenges to take up? Things that you can incorporate into your lifestyle in the long run. Suggest challenges, and if I am sure that they will benefit me for sure, I will take them up for at least a month. Thanks in advance!
