Sorry. I can only press like one time.
1. Don't buy into the hype when a new extension comes out (one new extension out of many may be worth some investment). 2. Don't handreg topical names like OsamaIsDead.com etc..thinking you can flip it quick here or anywhere, you just look foolish. 3. Stretch, go for long walks to lunch, drink lots of water/juice while sitting in front of your computer all day. A cold beer at night will keep you working.
Balance your life, Work is important but spend time with your family and friends. Life is short don't be all about domains. You will have a fresh and better appoach if you balance yourself.
