Running is undoubtedly a healthy lifestyle，but it is difficult to stick to it.I still remember one 50-minute run in particular in the spring of 2018.I made a detailed plan at first and immediately began creating a long list of excuses as to why this was simply just not going to work，why I wasn't fit enough and why I would fail.I was afraid that I had no confidence in my plan.Before I even tied my shoes，I'd already convinced myself I couldn't do that.
   How would it go？I had quit the workout mentally before I even started.Who knows how many times I stopped and restarted my watch？I spent an awfully long afternoon sitting by the road feeling sorry for myself.One bad workout would even upset me for days.I questioned my fitness gradually and cut more workouts short.And pretty soon，my fitness gradually came to a steady level or moved backward.
   The problem I gradually realized was that I treated my entire training plan like a tempo （節(jié)奏） run—hard，fast，strict.In a tempo run，if you don't hit your pace early，it's nearly impossible to catch up.Therefore，I realized I needed to treat my training like my favorite workout：the long run.I love ignoring my watch，settling into a relaxing pace，enjoying the route and focusing on only one goal—finishing.I love that I can have a bad mile in the middle and still end up strong.
   Now，when I set a new goal and write a new training plan，I have what I call "the long-run mindset".I find success and value in my training because I'm not eager for immediate results as before.Yes，there is still an important place for hard fast tempo runs，but I have shifted my attitude to thinking bigger than short-term outcomes and work towards lifelong success.
