If you attribute success to only you, you shouldn't expect it to last very long. Entrepreneur and author Scott Belsky points out that success isn't the result of one person's actions.

When you don't realise you'll always need the help of others, you're dooming yourself to failure:
Success corrupts and limits potential as soon as you start to think you could do it alone.
We don't like to let go of success. It feels good to get it right now and again, and it makes us feel capable. But it's important to remember that success doesn't happen in a vacuum and that you can ride the wave forever. You need to keep moving, and you need to keep enlisting the help of others. Appreciate what got you success in the first place, and you'll continue to have it throughout your life.
