My biggest piece of advice... uni goes by way too fast!

Very true, @cerianharries!

I recommend The Seven Habits of Highly Effective People by Steven R Covey, which your post reflects.

I also recommend that you write a personal mission statement – and make it a living document which you revisit daily, weekly, monthly, quarterly …

You can use this to hold yourself accountable, to assess the extent to which you are making progress towards your personal and professional goals.
