This is a favourable time for marriage proposals and new relationships.
Don't be afraid of criticism. Sure, some if of it will be negative or designed to hurt your feelings, but a lot of it will be helpful and give you some important things to think about. You can avoid criticism if you do nothing and say nothing, but that is clearly a very unfulfilling way to live. Instead, learn to sift through the criticisms that you receive with curiosity, picking out the helpful parts and discarding the rest.
It's easy to dwell on the negatives, but it's far more productive and beneficial to focus on the positives.
