If you want to help yourself emotionally and mentally, help someone else. I don’t mean by writing a check. I mean by volunteering, or physically doing something that needs to be done, or by coaching, or by supporting. Your degree of success isn’t as important as the energy of your attempt. You’ll feel much better about yourself, and it requires no monetary investment.
Mindset: Your most valuable asset is time, since you can always make another dollar but you can’t make another minute. Providing your time is extremely generous.
