You need to understand what caused the fall. Until you understand it's all superstition and therefore fear. You don't want to end up like a primitive culture, sacrificing an animal before going out on a ride because the last time you sacrificed an animal before a ride you didn't crash. One didn't cause the other, they just happened to be correlated.

So figure out what happened to make you crash. Once you understand that you'll be in a much better situation.

You'll also want to be conservative in your equipment and riding choices. This means that you should understand what could cause you to crash and to take steps to reduce the chances of doing so. For example have you checked your chain? Do you know what to check? One of the most common causes of surprise crashes that I've seen is either an improperly installed new chain or a totally worn old chain. They'll fail in an instant but will give you plenty of seeming random warning before they fail.

Other low-chance but high-damage items are bars, stems, forks, front tire/wheel units, front skewer, front derailleur, brake cables, chainrings, pedals, cranks. Make sure they're all installed correctly and in good working order. Most of the other stuff can fail without hurting you too much. When the above parts fail it can be disastrous.
