Depends. Speaking from a lot of experience being a socially awkward guy, the following helps:

• Improving fitness and wearing clothes that show it, getting rid of any terrible haircuts.
• Having standards other than appearance and focusing on that from the start. This means rejecting attractive people who aren’t a good personality/etc. fit. Why does this help? It leads to better conversations and less wasted time.
• Attitude of trying to laugh/have fun/be fun. She’s not into FOSS and motorcylces? Ok, don’t keep bringing it up then, instead talk about something you both like (and if you followed the above, there should be something).
