Momentum is what happens when consistency starts paying rent.

For a long time, consistency costs you and gives nothing back. Then at some point the accumulated repetitions start returning value, the work becomes easier, the results start appearing, and other people begin to notice. The change is not in your effort but in the fact that what you built has begun to produce.

If you are in the paying stage, that is the normal shape rather than a sign of failure. Keep the amount modest so you can sustain it long enough to reach the other side. The turn tends to arrive later than people expect and then quite quickly.
