I think all of us have times and places in our lives that we can look back on and chat with friends about --that we would refer to as "the good ole days". I think it's a lot of fun to reminisce and look back in life -- but it stops being fun if doing so hinders our ability to look forward or even find joy in the present.
When I think about my CrossFit journey it is 6 years of ups and downs as life has brought circumstance that would "halt" or "stall" my progress. We get stuck on the "I use to be able to do _____", or "my max use to be ___". You know what I see though? I see that over the past 6 years my fitness has been a priority in my life. Sometimes I'm more motivated than others, sometimes I'm fitter than others, sometimes I'm proud of myself for completing a workout even though I needed to lower my intensity to 60% because my mind couldn't take it that day.
I could care less what the whiteboard says - I don't care who is doing what next to me. I just want to model a healthy lifestyle for my kids and I want to take care of my body because I only get one of them and I want it to last. So if you find yourself looking backwards, what are you looking for? Your best days are ahead of you -- if you can simply embrace the present and set realistic goals for your future.
