One thing I have learned about myself is that I need a coach. I will never challenge myself enough or be creative enough without the help of others. If I am getting into the pool by myself I will swim for about 10 min and be ready to get out. I can just go through the motions and while it is better than not swimming at all, that type of "training" does not help me swim my best or meet any goals. I have had different coaches over the years. I also have my swim partner who challenges me and encourages me to do things I would not do by myself. I also follow other swim coaches online and read articles and watch videos about swimming. I look up different workouts online and ask other swimmers what they do to train. I mix it up and do different things that I would have never thought of on my own. You don't have to do this alone. Find others who have done what you want to do and learn from them. This will help you meet your goals and help you meet some great people. It keeps it interesting and helps you stay motivated.
