Following ideas may help in shaping one's career :
1. Don't try to get it right in one big step. Just get it going.
Don't write a book, write a page. Don't create the entire presentation, just create a slide. Don't expect to be a great manager in your first six months, just try to set expectations well. Pick a small, manageable goal and follow through. Then pursue the next.
2. Do what feels right to you, not to others.
We become what we think. It's not important what other's think of you But 'what you think of yourself'. If we think we can succeed, we will ... All in our state of mind.
3. Choose your friends, coworkers, and bosses wisely.
Critical feedback is helpful as long as it's offered with care and support. But the feedback that comes from jealousy or insecurity or arrogance or without any real knowledge of you? Ignore it.
