Good use of travelling time
It is easy to ignore time spent travelling in your assessment of time management. It is worth considering whether this is time that you could use usefully.If you commute by train or plane, are you using that commuting time to good effect? You may find that if you upgrade your ticket you get a more effective working environment. The extra work that you achieve may be worth the extra cost. Similarly if you drive you may find that it is cost-effective to employ a driver if you can work from the back of a car.
The value of this does, of course, depend on you using this time saved effectively!
You may also consider the condition in which you arrive to be important - if you need to be in good condition when you arrive, then you should travel in a sufficiently comfortable way.
