"Have patience with all things, but chiefly have patience with yourself. Do not lose courage in considering your own imperfections but instantly set about remedying them -- every day begin the task anew." ~ Saint Francis de Sales
Do not for any reasons condemn yourself; that you made it thus far is a very good sign you will surely get to your desired end.
Be proud of your accomplishment at the moment, and be patient in seeing other accomplishment materialize; it may take longer than expected but just keep working.
