Limits are in the head

Early morning swim covered 2,700 m - 1 year ago I was worried about completing 750 m and 1 year before that 40 m. I had a voice in my head telling me I couldn't do it.  Today I heard two very large ladies discussing completing 50 metres and how good they felt.  They had set it as a goal, planned their training and succeeded - now they are aiming for 100 metres - that's breaking the limits in your head.  If you have the desire, and that's the secret, put together a proper plan with someone monitoring your progress then you're on your way to raising the bar and silencing the voice in you head saying you can't do it.  Go for it and have fun on the journey - I certainly am.
