If you want to be a consultant, you don't need any skills except maybe make a few powerpoint presentations. You also need to learn the lingo. Be sure to wear a suit and tie at all times and pepper your speech with these choice words and phrases:
Moving forward,
Righstizing,
Rationalize,
Touching base,
Syndicate,
First to market,
Synergy,
Think outside the box,
Ping,
Low hanging fruits,
Apples and Oranges,
Cloud,
Bandwidth,
Facetime,
Let's take this offline,
FTE,
Work smarter not harder,
Quick wins,
Efficiency,
Deliverables,
80 20 rule,
Leverage
Lever,
Core values,
Alignment,
sea change,
gentle reminder,
It does not matter if you don't know what these terms mean, the more you use them, the higher you can charge for your daily rate.
Now if you will excuse me, I need to think out of the box for some low hanging fruits that I need to synergize and syndicate for some quick wins.
