Work Under PressureAs you may know that being an designer, deadlines are the most important of your career. As a designer you are always going to be under some kind of pressure to get things done. If you want to sit back and do things whenever you get around to it, find another profession. If you like pressure, and a challenge, and you like to solve problems effectively, then become an DESIGNER!!!
More on the DESIGN than the SoftwarePhotoshop and Illustrator don't make you any more of a designer than having a Paula Deen cookware sets makes you a world class chef. Don't lose your head. If you have a great computer, and your software gets the job done, then don't worry about it. On the other hand, if you are using an ancient laptop, and your hardware and software are severely hindering you, then you might need to consider upgrading.
Designers are always striving to Improve
Successful designers are always one step ahead of you. They were doing responsive website design when you were learning HTML and CSS, and they will be on the latest in design when you are learning responsive design. You can always improve. The more you know, the more you're worth. If you have a wide range of skills, and you excel at them, you can charge a lot more, because clients will still save money over hiring a large firm.
