Nicely said! Though first learning curve is mostly the fastest. Most people tend to get enough motivation from the first few weeks of learning something since they can see the improvement weekly or even daily. The hard part comes when you can't see your improvement.

The solution is to write a physical goal down such as: write everyday and complete 200 pages in a month.
Now you have a tangible goal. The only goal you have to focus on is reaching those 200 pages. You don't have to focus on improving and you don't have to compare yourself to others.

What I experience is that this makes the proces much more fun and rewarding, since you create these short term milestones.
