As someone who did traditional first, then did digital afterwards, the former is WAY more important to practice a lot with. Reason being, I have seen people who drew digital first, but when asked to draw traditionally, most couldn't handle it or struggled with it since they were too use to having the advantage of using the undo-button and stuff to adjust their works.
With traditional, if you are using paints like watercolor, acrylics, etc... as well as ink pen, you can't erase it so you pretty much have to use your brain to problem solve and figure out how to make that 'mistake' a part of your work.
Honestly, I'm still struggling with digital due to the fact that layers tend to confuse me when I work and, for some odd reason, working on the computer tires me out WAY more than drawing traditionally. Not to mention, it feels like I can't focus at all in trying to complete works really.
I actually really want to stick with the former, but because all the cool kids do digital, I kind of feel like I have to do that in order to get noticed and stuff (like, traditional is 'old fashioned' while digital is something everyone wants more of...).
To answer your questions though:
Is drawing digital easier or at least less frustrating? That depends on you and your learning speed. Having traditional media knowledge on hand, it lightens the learning curve, but it's kind of a different beast (no pun intended!) altogether so... (For me, I find it hard really...)
Should i keep drawing traditional to get better? Big definite YES here!
If i am going to start digital drawing then what steps should i take? Investing in a pen tablet helps, imo. Because pretty much everyone uses it and it's pretty much a requirement. For digital programs, I would suggest finding free ones like Fire Alpaca or Medibang Paint as they have limited features but do a pretty good job in getting started. Then if you want to try what everyone else uses like SAI, Clip Art Studio, or Photoshop, either save up or... do the illegal means (the latter is your choice but...)
What tips could you give a novice about drawing? Besides drawing a lot... Try to like draw stuff from life and copy from books for practice and stuff. I honestly recommend (if you can find a nearby class that you can register cheaply) life drawing classes aka studying naked humans because it will teach you some basic anatomy and quick sketch studies which is helpful for if you want to get an idea or thumbnail and gesture down. Drawing still lifes too. Also, find out what your attention span and your comfort zone is because art is such a huge mental strain, that you find you might end up a little insane from trying to figure out if you are improving or not, lol. Oh and, find out what you like to draw because usually that helps keep the motivation going in trying to improve yourself.
I hope this helps, and sorry if it got very wordy here...
