Timid, but shouldn't be

The recent sell off has me tempted to shift my savings into my trading account, but part of me is reluctant to. I get the feeling that now is a good time. Illogically though part of me wants to wait till I have more money in front of me, so that I can buy in a preplanned spreadsheet specified fashion with a minimum of transactions. Though commissions are low enough that it'll probably cost me more to wait, unless the market takes a more serious tumble.
