It's absolutely important to keep growing and developing yourself. I really like the example of Neil Strauss, who had an interesting development that he documented in several books over a decade:

Start out as a guy with no romantic life, clueless about women.

Develop into the world's greatest pick-up artist and started relationship with famous female singer.

After several monogamous relationships, explore all arrangements of polyamory and alternative lifestyles.

Return to one woman, declare his true love and build a healthy, monogamous family with her.

What a journey eh?
