<human>: Can you succinctly summarize the text in 1-3 sentences?

I used to run regularly, 4-5 times a week, 2-3 miles each run. I did this pretty consecutively for almost 2 years, and I made so much progress over time. I increased my speed, my distance, and endurance and I would continue to try to improve my runs whenever I could. I stopped running about a year ago because my schedule got way too busy, and I didn't put in the effort to fit running into my routine anymore. I'm now REALLY wanting to start again, but the thought of losing all of the progress I made over time makes me hesitant in doing so. I also don't seem to have the motivation to just start running again even though I want to. I've honestly gotten lazy over time, and my eating habits have worsened as well. I want to change all of this and start running regularly again. Does anyone have personal experiences with a similar situation? How did you start running again? Any advice would be greatly appreciated!
