Look for opportunities, not obstacles.
Look at the long term gains vs. the short term wins
Don't Fish for Whales.
Don't confuse results with action/motion.
Kill your biggest time waster.
Find someone/where you can work WITH. If they do everything they can to enable your vision & success - make sure you reward the opportunity with results.
Have a plan - but flexibility & adaptability are vital.
Don't forget to plan time for you.
Patience & Observation: You need them.
You have to start RIGHT NOW.
If you change careers: Immerse yourself in the culture, industry, etc. Absorb as much as possible. Practice/Recite/Prepare.
