Analytical types typically suffer from paralysis by analysis. They always need more data, more comparisons, more thing to think about before they make a decision. Naturally, the decision rarely comes and the thinker believes they're making progress as long as more data is collected. The problem is that this isn't progress, it's imaginary momentum.
Momentum only comes from action, not from analysis. The best way to get momentum is to start making decisions, taking action, and following through. Even if it's just deciding what you're going to eat and taking the action to eat it, that creates more momentum than thinking about it.
