Have many fingers in many pies

Give yourself as many possibilities, chances, plans of attack and opportunities as you can. A working example is myself at the moment. I know I need to make up some kind of income now to replace my wages; the buzz is in knowing it is completely my responsibility. I am not relying on one single thing to pay my bills- I have no less than six projects to generate income to begin with.
Therefore I give myself more chances at succeeding. Or if one or two fail I can learn from that and still have 4 or 5 that are working for me.

I think of it as casting many fishing lines. There's a higher probability of getting something back.

It works exactly the same for many things-
Marketing- write, prospect, email, call, contact, bug as many potentials contacts, institutes, associations, colleges, friends, family as you can. You never know who knows who- a friend of a friend might just be your next big sale.

Never pin your hopes on one thing- increases you probability by increasing your fingers in pies.

If you want a new job, don't just settle at applying for one that seems suitable or ideal or perfect from job night in the paper once a week and hoping for an interview…get a plan of action. Apply for jobs that only seem slightly suitable, get searching jobs on the internet where they are updated daily. Write to companies you would like to work for out of speculation- asking if they happen to have or know of the particular position.

If you get bored with things easily, lessen the chance of being bored by having several interests.

Yes it means being organised, or working a bit harder, writing a few more letters, making a few more calls- it's worth it when you achieve what you set out to though!
