Some get it just after a trial, others many trials. Always remember that your case or situation might be different and you might fall into the harder category of individuals.
Don't even think of stopping if it didn't work out the first time, just like some did, it is okay to ask questions, ask for help. It is okay to get mad and angry sometimes too as to why things seem harder for you to achieve. But in whatever you do, don't quit or stop working.
The stupidest thing a person doing is quitting work because of laziness or emotion...
We live increasingly competitive, each of us and also our families need food and shelter, how do you meet your daily needs if you are lazy and don't want to work. Look at how sad the life of beggars is who are young but are lazy and don't want to work, they finally have to live on the streets.
