Things you don't know and find difficult, don't hide from them. First understand clearly, then master them. You'll be much better than others because most people are unwilling to put in the effort to study deeply, and they will be automatically eliminated. So your persistent effort will give you a big advantage. Don't bother or rely on others. If you don't know something, go learn it, look up information, watch videos, and explore slowly. No matter how difficult the process is, it can eventually become a skill you possess. Always think about cutting corners; difficulties will only increase.
