In the society right now,it will be good for someone to learn a skills or know a skills because they are very important in making success easier for us and also make us use the skills to make money and make life better
There are plenty skills that someone can learn depending on what the person have passion for,as for me in some years go i went to learb music production and i was good at it and during that it gave me an income that was able to sustain
I cannot say the specific skills which you need to learn is because what i might suggest to you might be something that you do not have interest in or have passion for so that is why i will just simply tell you that you should just learn a skills that you have passion for and make sure you concentrate on it while learning it
