For me personally, a new diet and exercise has made an amazing change in my life. Changing habits is the hardest milestone to pass, but once you work them out enough that they become something that doesn't come with difficulty (you just approach it like brushing your teeth every day), then you're a winner. In addition to taking care of mental health, you also win having more energy, 'healthier aging', etc. Don't get me wrong - it took me few months to get those two things to this point. The other side of the coin are social relations - I don't keep negative people in my circle of friends (it exhausts me mentally). Further steps will start to appear by themselves :) - cool projects, new groups of friends which whom you feel the same vibe, professional opportunities, etc. I really do believe in that
