1. The wisdom to accept that you are unlikely to ever work in middle / front office.
2. A tough rear-end – you are going to be shouted at, blamed and verbally abused every time something goes wrong – even if it’s not your fault.
3. Resilience – you will be able to deal with high work volumes and often have to work under pressure, and to strict deadlines.
4. A realistic and accepting nature – you will rarely be complimented for a job well-done, and you will certainly not be the one earning the big bucks at year-end.
