2. I will be a little tired at first, and I often work outside, but my salary is very high.
3. It will be much better in a few years. If you add your own efforts in five years, you will soon be promoted to middle and senior technicians and your salary will be higher. In addition, it will take some time for such a unit to play its role.

I hope it helps you.
