When I was 17 and first started going out for a drink with my friends, I didn't like the taste of beer. So I went onto Guinness every Saturday evening for about 6 weeks, which is beer on steroids taste-wise, and at the end of that time I could tolerate it just fine - but ordinary beer tasted wonderful. That was quite a life-lesson for me, because I learnt that
- Persistence is important in overcoming difficulties.
- Things may present themselves to us in a particular way, but a change in viewpoint can make them seem very different - and that can lead to very different judgements from us.
- It can be hard and take time and some work to see things from a different perspective, but we throw more than half the world away if we don't suspend judgement and put in the effort.
- This isn't just about beer, but about all the great issues in life - politics, religion, choice of work, choice of partner, learning a complex skill etc.
- But it's equally good for the little things - I learnt to drop sugar from my tea and coffee this way about 10 years later, and again they tasted awful at first, but persistence paid off. They taste awful to me with sugar since then, and great without.
Yes, but when I was an IT manager I learnt that the emphasis for personal development of myself and those in my team was to develop from our strengths and put most attention into those. That's how you develop highly performing teams. Weaknesses don't get neglected, but they should't become the main focus - in fact people who put too much effort into trying to eliminate their weaknesses tended to under-perform. I'm good at maths, but not very good at drawing, so I'd be wasting my time focusing on drawing at the expense of my maths.
But of course you are focusing on moral, health-related or happiness-destroying weaknesses in your question. We all have these at some point in our lives, and if others are like me, different ones in combination at different times in our lives. As well as the persistence I talked about above, I think moderation is really important - the middle way between hyper-indulgence and deep asceticism is the path to success for me. I'm not sure about the idea of punishing yourself for a failure - maybe that works for you, but it does feel a bit like a Harry Potter house elf beating themselves up for a sin against their owner. It's not a bad idea though - in moderation. But at the end of the day, persistence, a determination not to give up, a change in perspective brought about by taking on new contrary habits - these are the sort of things that work for me.
And Oh yes! - a sense of humour and a good laugh at myself if I keep slipping up and get too intense about something I'm struggling with.
