Begin while the idea is still inconvenient enough to prove you mean it.

Convenience is a poor test of commitment, since almost anything is easy to start when nothing is being given up. Beginning while it is still awkward, while the hours have to come from somewhere real, is what establishes that the intention has weight behind it.

Do not wait for the season when this will fit comfortably, because that season is largely imaginary. Find the two hours now, from something you would rather keep. The discomfort is the evidence.
