Getting organised

Thinking in post-its.
There’s nothing like an exhibition to highlight the need for being organised and having good systems in place. INTERPLAY, opening in early November, is no exception.
Playing with post-its and the Johnny Decimal system I’m currently looking at the following areas and categories to organise the files on my laptop:
10-19 ADMIN
11 Legal
11.01 Contracts
11.02 Company Registration
11.03 Etc.
12 Accounts
12.01 Invoices
12.02 Expenses - Business Only
12.03 Expenses - Shared
12.04 Bank Statements
12.05 Etc.
13 Planning
20-29 MAKING
21 Works
22 Writing
22.01 Proposals
22.02 Newsletters
22.03 Articles
22.04 Artist Statements
22.05 Bios
23 Research
24 Exhibitions
24.01 Interplay
24.02 New Old Forms
30-39 MARKETING
31 Website
32 Social Media
33 Branding
34 Promotional Material
34.01 TAD
34.02 Exhibition Invites
40-49 MONEY (SELLING / INCOME)
41 Inventory
42 Lists of Works
43 Potentials
43.01 Sales
43.02 Funding
This structure is not complete and is very much a work in progress. While the idea of a perfect system can be both seductive and stultifying, I know (sometimes with difficulty) an imperfect and working system is more practical than an illusory idea.
