Constant reassurance and acknowledgement

I have the habit of seeking constant reassurance and acknowledgement from others about anything I do.For eg. I wanted to take up yoga classes during lunch hours at work and I wasn’t able to decide if should do it or not.I had thoughts like ‘ Can people workout during lunch hours at work’.Though many of my colleagues said it’s fine to do it. I kept on searching for more acknowledgement.I find similar situations in many areas where I seek reassurance from others and don’t decide on my choices.How do I make better decisions on my own ?
