A very good thing in the IT industry is that it is a very live matter, which means that everything is changing really fast. Big part of that positive change are software engineers, especially the ones that love what they do and are motivated and inspired to always become better.

Challenges for developers

Successful software engineers have to keep in touch with modern technologies, always improve and expand their skillset and knowledge. In order to achieve that, we should be fully dedicated to what we do.

How do we get better?

Successfully combining youth and experience is the key. Here are just a few of million advices, that will, in my opinion, make junior developers "grow", and keep "growing" even when they become seniors.
1 Solve your problems the right way. Don’t work around the problem and deliver a quick fix. It will backfire on you.
2 Commit your code at regular intervals and push your code at least once in 2 days. Don’t have a lot of uncommitted code in your local environment. You never know when the system is going to go down.
3 Externalize all your static variables. This will come in handy, when you are trying to localize your software.
4 Adopt a common code-style for your team. Use it!
5 When in doubt, always ask. You never know what other members of your team know. Never underestimate anyone.
6 Write pseud code or your logic on a paper before writing code for it. Saves you a lot of time.
7 Never underestimate the importance of code readability. Your code is your introduction. Write code, which has meaningful variable’s and function’s names; follow a coding standard; properly indent your code. Code organization will multiply your work value to a very high number.
8 Get your code reviewed.
9 Be open about criticism regarding your code.
10 Do not write code that you won't need. Because you will be responsible to maintain that.
11 Every good organization loves and rewards a loyal team member. Do not leave a good company or team for a few bucks. Money will come. But good bosses and teams are hard to find.
12 Choose a job, where you can get the most experience and gain the most skills instead of the best paid job.

Last but not least:

Don’t hesitate to learn new technologies. Get out of your comfort zone. That’s how you survive in the software industry.
