What is your opinion on this piece of advice?

That's the way I've lived my life since my mid 20's, after the one person in the world I loved with all my heart was killed. I realized this was the only life I had and I was miserable-and the only one who could change that-was me. I changed jobs, moved, left my husband, and started doing all the things I had always wanted to do-and did them. I still made mistakes, but am now with someone I love with all my heart, and have no regrets. I can die happy-knowing I've done the things that were most important to me. Go for it!
