There's all kinds of advice folks could give, but in the end it's like everything else in life, experience buffers out the extraneous stuff. Just keep riding. Also like everything else in life, if after some time you just cannot make it happen, well that's just The Universe telling you you're not a cyclist and there are worse things.
My only specific advice is to invoke the Ray Bradbury Principle**.
