People generally do want to lend a hand. All you have to do is ask. Allowing others to give to you is also giving them a gift because it creates a balance between giving and receiving. When you ask for help, you are signaling to others and yourself that you are ready to receive, expand, and enrich your life.
Here in the United States we are especially weird about failure. We're a nation that values wealth and perceived success over mostly anything else (as the current political events prove). We hate weakness, vulnerability and what we perceive as failure. But I think that is a mistake. Not only does it make us extremely superficial, it also robs us of an opportunity to reflect and learn valuable lessons.
