In your quest for future success you will have to overcome some obstacles. How many of these aspects of gaining success is true?

Needs a few others:
You will doubt others.
Others will sustain you.
You never think you're good enough.
You will help more people than you'll remember.
You'll frequently wonder "Why God?"
If it were simple you'd find something harder to do.
The list can go one but I like the topic.
