I'm in this industry for almost seven years now, and I have seen many successful developers. But I have also seen many people quit.
Besides the developer's life, I'm also a tutor, and have taught over 50 people how to be a developer.
I could see what the successful students did and what the unsuccessful students did.
This is not a guess. This is what I witnessed.
It's not easy to make a career transition. It's not easy to start coding and learn all of these terms in record time. Maybe you are doing a Bootcamp. Maybe you bought dozens of courses on udemy. But you did not finish any of them. This is because you do not have the real motivation to do so.
What is your main goal?
Know yourself better to answer this question, and when you start to be lazy remember your goal. It should be greater than anything else in your life, and if it's not enough, perhaps code is not your thing.
People that succeed in dev career are truly motivated. They know their limits and always try to be motivated when a big challenge comes to them.
Which tech do you want to work with? React? Node? Flutter? Man, you need to choose one! Be focused, don't let others decide it for you. Watch the market and choose what you like most, and what is in demand. Focus on something and stick with this tech.
I say "watch the market" because if you prefer to work with Fortran, maybe it'll be hard to find a job. Really. So, choose something in demand which you like to work with every day.
There is no problem at all to be a full-stack and know other techs, but if you are starting a career in tech, choose just one.
You're gonna hear a lot of "no's" before you get your "yes, welcome to the company". You'll hear a lot of things about your non-existent experience, and even maybe about your code.
These things happen and you must be strong enough to handle them.
Again, remember why you are trying to enter this industry. Do not give up on your first "no". Learn with your failures and try to improve for the next time.
To get a first dev job is not easy. The market is good but not that good for juniors developers. It was hard for everyone. You need to continue studying, improving your portfolio, and showing your job to the world.
Learn about how to make a nice resume and a good LinkedIn profile. Believe me, if you work hard and really understand what you are doing on your projects, it is just a matter of time.
Most devs that I know started to code because they find it fun. It was a challenge, a nice thing to do on the computer.
Find your fun in it.
Create nice projects and have joy in the process.
Maybe a new youtube only for kitties and puppies, why not? Create. Learn. Have fun doing this. Studying should not be a boring thing to do.
I wrote here five skills that I have seen in successful devs that I've met, but my favorite is: "have fun".
If you can have fun while you are doing something, you're already ahead of the game. Things can be really easy when you enjoy what you are doing. Find what makes you happy and invest time in it.
When I started I had bad times on MySQL and I decided that I did not want to do that for my whole life. So every time that I got pissed off with that I switched to CSS, because it made me happy. At that time I noticed that I should work with CSS and forget about MySQL.
Years later I'm a front-end architect and I still loving CSS.
