My stride to Career

So lately, I have been slowing down, and I have a reason for it.
From the beginning of this account to right now, I have been building everything in sandbox mode, the only problem being that I'm a free version user. sad. Bc of this, I cannot edit most components, engines, propellers, etc... , so i'm bottlenecked by this. In the next 4 months or so, I will be striding to playing career mode often to be able to improve my crafts. yes, this means i'm putting more load on myself, but it will be very worth it. this is for the good of you guys too.
Thanks...
