our capacity to learn

Apparently we could teach ourselves anything. Given enough time, resources, correct attitude we should be able to learn anything out there. Our brain should have enough capacity to learn whatever other people could do. For example learning foreign languages. For sure some foreigners are able to communicate using that language and since they are human being like us, with the same brain is we have that would mean logically we could learn their language too. Of course some languages are harder to learn, and our own condition could also poses extra challenges to us (for example dealing with sounds that we do not have in our mother tongue) but of course if we are persistent that would not be out of our reach. Eventually we shall be successful. 

I haven't started learning anything new lately, but based on my previous attempts (mostly in learning languages) I could see that the biggest challenge is finding the motivation. Basically we need to answer this question of what's in it for me? Why should we spent times and effort learning this skill? Would it worth our effort and sacrifice? Without the motivation we would easily give up or making excuses. 

Once we identify the necessity we should certainly be able to be persistent. We might still experience frustration but knowing that this endeavor is important for us we would certainly find ways and solutions. We would ask around, buy books, browse YouTube etc. In the age of the Internet chances are someone would have posted what we are looking for somewhere. 

The other thing that we need to consider is the need to have enough resources. Imagine learning piano without ever touching a real (or virtual) piano. Piano skills needs hand coordination that would typically be mastered by hours of exercise playing the piano. I would think some skill would necessitates us to exercise manually and not just imagining working
