Someone rightly said you can't do much carpentry with bare hands!! You need tools. To be good at carpentry you need the right tools. To produce something good, your bare hands aren't just enough.
Same way, as you walk your way to be an engineer, just knowledge isn't enough. Only knowing how the aerofoil generates lifts or solving bending moment problem isn't enough. To be effective as and engineer, You need tools.
So as you are walking towards the path of getting your degree, and if you are in your penultimate semester, start getting those tools.
Tools along with the knowledge that you are acquiring during this phase of AeSI will make you the coolest carpenter around when you graduate!!
