The second half of the sentence reflects your own mentality. Since you have filled the TA and made it yourself, it shows that you drink freely, need others' attention and want to attract others. And you want to express your "generosity" at will, and use the side to show that you are stronger than you. Being able to drink is also a skill.
The whole sentence shows an idea that people show when they live for themselves all their lives. This idea has always existed. Only by correcting this kind of thinking can we be "true". Personally, I think this sentence can be written from the opposite side. Everyone wants to get rid of the individual-centered thinking for others and open his heart to someone, something and something.
