Receiving the feedback from my boss and my mentor was easy - they are all very positive. Those that are not, they have been work in progress.
But I'm going to push my limit further - I'm still not satisfied with where I am now.
A few learning points for 2017 (which haven't ended yet - I might have an update) below, however:
1) Never be afraid to speak up - be it on a new, more efficient approach on doing things (ofc, research them well first before presenting it), be it saying no and pushing things away (due to lack of capacity and inevitable compromises of quality), be it asking for help (you'll be surprised on how people are happy if you ask for their help as they feel that they're worth much more than they think of themselves). You need to speak up to get what you want. Nobody can read your mind and nobody will know what you want unless you say it out loud.
Moving forward: Learn to be more tactful. Learn to speak with confidence in front of a few more people than just one
2) Feeling the impostor syndrome? It's completely all right - even the most qualified feel so. When you have this feeling, do not doubt yourself more than necessary. Keep pressing on as you're probably on the right path - if you're not, you'll know it before long from the people around you. You'll be surprised on how the feedback loop is automatically created - people are just busybodies.
3) #humblebrag is absolutely necessary for your career to move up. While keeping the balance between doing it and overdoing it is tricky, it's always better to make sure that people are aware that you were the one who did it, if you really did. Give credit when it's due, not when requested, even when the person is not accepting it. Fundamentally, people are always grateful that their efforts are recognized. Overdoing it really makes some people's head so much bigger though.
4) Own up your mistakes and deal with the consequences too. But remember, the consequences are not always because of your mistakes alone - large companies have a blame chain reaction that especially ends up in you if you "humbly" accepts that that might have been the case. Know where you contribute to that, know where you are not. Know where your place is and you'll be fine whatever your mistakes were.
5) Do not bite more than you could chew. There's nothing more frustrating for the people you've promised to deliver and you didn't. Always underpromise and overdeliver - never overestimate yourself.
Cheers to another month of 2017.
