This interaction of Okarun not to interact with a girl who really talked with him literally a day before, is something I used to do or maybe even now.
So what is this behaviour? Introversion? Social anxiety? Shyness?
I enjoyed the scene because it's relatable but also it got me thinking why do I react the same way.
Did you relate to this scene? Did you grow-out of that phase of ignoring girls unless they interact?
(I know all of this little cringe to make a post upon, I'll delete this if it doesn't fit here)
Good on you. Something that I feel helped me is using the skinner box reward tricks and things that corporations use to get us hooked (fake points, etc). They use it to keep us engaged, so I tried to use reward systems to keep me going. For example, I can have a cheat meal, if I lose x lbs. If I talk to this person or this group, I will buy myself something or do this activity that I want to do, but have been putting off. You can get a calendar and mark down days that you worked on yourself (any info about that day that was unique? Write it on the calendar). Looking back after a month and seeing the days add up, makes you want to keep going.
Plan > execute > evaluate > make needed changes and try again.
Remember you are growing and adding skill sets to your current ones. Each day you do this you can get a little bit better. After a while of doing that, you will be amazed at how much you can change yourself.
Take rest days too. We need little breaks too. It's like bashing your head against a wall when you're trying to down a Dark Souls boss. Then you quit and take a nap. Come back and 1 shot them.
