Those initial mental hurdles are the most difficult to overcome. "I can't ride in the rain." "I can't ride in the cold." Etc. But once you've done it...suddenly it's not so scary.
Those first couple of weeks of commuting can be a mental hurdle as you must often will yourself to the effort to bike, if you're not already in shape for it.
Great job, and keep it up!
