It is certain that I can potentially enjoy any project whose idea inspires me. It can be from a simple buzzing system that prevents me from slamming the fridge’s door with an open drawer to a sky rocket algorithm that quantifies soft tissue deformation during pitching. 
I’m an engineer and researcher. Therefore, I can do anything. Including doing nothing that I’ve done till now. How that sounds? Beautiful uh? If technology was broken for a certain research question, it was worth to evaluate how much I could put it together and how much I should wait for my beloved colleagues to come up with better material science that will hopefully fix the broken technology of today. 
I wonder how senior researchers and professors deal with it. I know some that keep a straight line of thought since the first derivative line in their phd. Some others are widely open to their students’ abilities and drives. The latter perhaps would hear me when I say that you can do whatever you want. 
Holstee and so many other inspiring texts claim you should do what you love. People may break nuts while figuring out what the hack is the thing they love. Maybe the answer is not a single topic or drive. It’s a realm. But watch out, you should not entitled yourself to a task that you don’t have the correspondent knowledge and qualification to do, this would be totally irresponsible. But yes, given that you have the background knowledge, that you know the right tools for the job, you can do anything. Do not ever ever ever step on someone else’s domain. Give value and admiration to your peers is essential and efficient. Also, do not deliver bold statements based on superficial knowledge and low fidelity data. Be critic. About your work, your mentors’ work and anyone else’s work. Do it, but find the line between being critic and wasting your time pointing out at others’ work. A nice way to show limitations of a given work is not pointing at it loud, it is indeed to do it yourself… better. 
Not only you should do what you love, but do what you know you do well! Know your weakness and find competent people to pair with, given value to their work. Remember that is always hard to give value to details or preciosities if you ignore the topic. Respect and admiration should fill your knowledge gap for this purpose. 
And yes, be in fucking love with yourself. This is essential, but do not ever ever diminish other people and do not put yourself on a tabernacle from where you are not be able to see what is underneath your feet or the dust around you. If you don’t love yourself, you can be ridiculous competent but you won’t be seen and recognized. Don’t wait or work for recognition, do what you think is needed and give yourself recognition for your strengths, efforts, and your processes of learning by failure. 
Be bold. 
Do what you think the world needs and if it is not prepared for that, build a communication tunnel which you could use to offer the world something, even if this is limited or far from your ideal capabilities. It is worth. Don’t attach and satisfy yourself with the minimum though. The sky is not the limit, but it’s a nice place to be looking at. 
Be bold. Mean it!
Driving, I’d tell my mom. If you are willing to turn, mean it, otherwise people won’t see your intention. If you don’t turn the wheels enough, you’ll either find an obstacle or be an obstacle to someone else. Mean it. 

a humble confession/collection of insights to my pupil that inspires me a bunch. Thanks g.
