One of the biggest mistakes I made in life that I wouldn't want anyone to repeat is to believe that all the people you helped when they were in need will stand by you when you also need them. Long story short I had an opportunity to help a couple of people when they were struggling, things got better for them and I had a challenge and I was hoping to get the same help from them since I helped them when they were in need but I was disappointed, abandoned and I regretted ever helping them.
