How to check your own aspirations
If you have had big problems in systematically learning up to now, it's the right time to have a look at your aims and your motivation. A good cause for not reaching an aim is because it is not reachable. (That means: If your aims are not reachabel you can't reach them).
The measure for your own claims shouldn't be theoretically possible or how an average person could do it. Your aims should be measured by your own success record, by your own possibilities. You will fail for sure if you plan to work ten times faster to make up for what you didn't reach with working five times faster. A realistic plan must take into account your own limits.
