fixed costs

why i'm pretty cash-tight (read: will be broke in a while) this month:
1. paid for my 3month visa which cost nearly 200USD
2. paid room rental until end of August
3. paid bike rental for 3 months until end of August
4. vacation and tours last month
5. new phone and SIM, and lost cash last month

At least, all my fixed costs for the next 3 months are covered. Only the variable expenses then has to be monitored, or controlled, which is exactly my problem. I can't say no to eating out and having fun. Haha.
