I get up early and some times

You can take a shot any time if you set aside the money to do so. For example, with your $100 roll, let's say you decide to allocate the next $10 you win. So, when you reach $110, you can take $10 and use it for a shot at NL10. If you lose it, you still have your $100.

Note that this applies to taking one shot once in a while. You can vary it somewhat; e.g. save up $20 so you have 2 x $10 buyins. But to play regularly at the new level, you should be fully rolled. 20 buyins is often suggested as a guideline. I lean toward 30 so that you have more room to absorb a bad run before you're forced to drop back down.

If there are 10 people waiting for one table and you start a table it will fill up quickly.

You will learn more starting tables at 4NL than you will playing under rolled at 10NL.

Just set aside $80 of your $100 roll, play 2 tables of 80BB 50NL. Justification? It's only one shot once in a while.
