Successful people want others to succeed while unsuccessful people secretly hope others fail. I read something like this a while back and it stuck with me. The point is we are all in it together. Rarely does someone succeed alone and even when it appears they did, they probably had someone (or a number of people) helping them along the way.
Athletes have coaches. And so do many business people and professionals. Musicians rarely are self-taught. The same is true for business people and professionals. Most of us were students who had teachers, whether in school, an apprenticeship, etc. You get the idea; it is rough going on your own and makes it much more likely you will make serious mistakes teachers and mentors can help you avoid.
I have been lucky enough to have formal and informal mentors along my road. Without them it would have taken me much longer to achieve many things I have personally and professionally. Or maybe I would have missed opportunities because I didn’t even know they were there, or not made it as far as I have.
So leave your ego at the door and help people in your life succeed. Not only will it probably end up benefiting you at some point (but you can’t count on that and it’s not the reason to do it), but it will make you feel good helping others. Plus, success really is contagious. Try it and see.
