Luck can help, but it is often overlooked. If you are honest with yourself, I bet you can recall a time when luck was on your side. Maybe it was meeting your spouse at a random art festival, guessing correctly on an exam, having your resume fall into the correct person's hand, or something else. From my experience, these are the best ways to improve luck:
1. Work hard and wisely.
2. Be kind, and have a sense of humor. If people like you, you will form connections and will more likely meet the right person.
3. Try new things. Go hiking if you've never been, attend special events downtown, or learn to dance. This will make you more interesting, helping you relate to a wide variety of people.
I wish you luck.
